BBoonEn/ Applicationfi lcdJ'uly 21,

This invention relates to chicken brooders and has for. its object the provision i'of-a simple and inexpensive device which may be readily manufactured and set up andwhlch will efficiently protect young chickens-"from cold weather. The inventionseeks to provide a device in.- which proper ventilation will be effected andwhich will permit free access of the chickens to and from thedevice and in which the interior will beof such construction that repairs or renewal of parts may be easily. effected. i

' The invention is illustrated in the accompanying drawings, in which. {-2

a Figure 1 is a view, partly. .in elevation and partly in section, of one ,fOIlII'Of my im proved brooder; and

Fig. 2 is a plan View, partly broken away, of one brooding chamber shown in Fig. 1,

In carrying out my invention, I provide a housing 1 which may be of any desired form and is preferably circular, assuch form may be more easily produced than an angular form. The housing comprises a vertical 5 wall defining a shell having an open bottom and. adapted to rest directly upon the ground or the floor of a, chicken house. This wall is provided with one or more openings 2 constituting doorways through which the chickens may pass to and from the brooding chamber, and a top 3 is supported by the wall and extends across the entire chamber. The doorway 2'provides a ventilating opening but, to assure complete ventilation, openings, indicated at 4, may be formed in the wall near the lower edge thereof at such intervals as may be desired, and in the roof or top 3 a ventilator 5 is fitted, which ventilator, as shown most clearly in Fig. 2, is of a damper construction whereby the circulation of air may be controlled. Upon the inner side of the wall 1 I secure an annular bracket or rail 6, preferably formed from an angle bar, as shown clearly in Fig. 1, and in the overhanging branch of this bracket or rail I mount hangers 7 of which any number may be employed as may seem most advantageous. These hangers are threaded in their upper end portions, as shown at 8, and nuts 9 are'mounted upon the upper extremities of the hangers and turned home against the bracket or rail 6 sothat the hangers will be properly secured and firmly supported. The lower ends of the hangers are turnedlateral- 5 1v outward to provide feet 10, and to the said feet a hoop or ring 11 is secured. A curtain 1924; Serial ism-727,304.

12 ofv textile fabric, such as a woolenrblanket, is-secured to and depends from the hoop, and-a cover -12- of like material isalso secured upon and extended over the area defined bythe hoop." The cover is, of course,

circular to conform to the shape of the wall 1- and the hoop which is located in proximity to .thewall. A hem is formed on the cover to receive and containlthe hoop and the cure tam-12 is attached to thesaid hem. The hem may be formed by stitching in a well-known manner and the In the larger sizes of the:brooder illus trated in the drawing, I providetwobrooding chambers which are duplicates in rc'onstruct-ion and between the said chambers I arrange a stove or heater 13, the upper portion of which is constructed to form a boiler or water chamber of any approved form. Extending from the boiler or water chamber 14' into each brooder chamber are circulating heating pipes 15which are arranged at the center of each chamberin the form of a radiating coil 16, it being readily noted upon reference to Fig. 1 that the circulat in the wall 1 and extend across the broodingchamber, as clearly shown, it being noted that a pair of beams is provided for each radiator and they are spaced apart so as to curtain likewise attached'to extend under the end portions of the radiator and thereby effectually support the same; without obstructing the circulation of warm air within the brooding chamber. 1

In use the air within the brooding chamber will be effectually raised in temperature by the heat thrown out by the circulating pipes. and the radiator sections of the same within the brooding chamber and will cir- I culate above the cover 12" so that all chilled air within the brooding chamber will be driven out and the fresh air flowing into the same will be raised to a proper temperature to maintain the healthy condition of the chickens. The fabric cover 12 will extend over the entire brood of chickens so as to protect them from direct contact with the 5 suflicient heat to prevent chilling of the chickens in the event that the fire in the stove or heater 13 Should get low. The curtain 12 will hang close to the wall of the brooding chamber and will thereby prevent theyoung chickens from coming into directeontact with the wall which is preferably of sheet metalv and, consequently, prevent chilling of the chickens from such source. It .will vbe further noted that the curtain hangsfreely so that it will yield readily tothe chickens which may be passing into or outfromthe brooding chamber and will I also prevent the air flowing in through the ventilating openings 4 from playing directly upon the brood. 'The device is exceedinglysilnpleinconstruction and access may be easily had to any of the parts which mayneed repairing or renewal.

.Havingthus described the invention, I claim: a v v At the same time, the woolen.

A brooder comprising a housing including a ciroumscribmg wall and a removable top, said wall havlng a passage 1n its lower por-- tion, an annular rail secured against the inn'er tace of said wall lntermediate 1ts depth 7 and having a flange pro ecting nwardly therefrom, a hover within said housing consisting'ofa hoop conforming to the contour of said Wall and extending adjacent thereto a textile cover stretched over said hoop and having its marginal portions secured about the hoop, a circumferentially extendingcurtain depending from'the marginal portions of'said cover and disposed close'to said wall, hanger rods disposed vertically and having their lower ends secured to said hoopiand their upperend portions threaded and projecting through openings in the flange of said rail,- and nuts screwed upon the projectedupper ends of said rods and resting upon said flangeto support the rods and permit vertical adjustment of the hover and removal of the hoverwith the housing.
